How do participants feel at the retro: Explorer, Shopper, Vacationer, or Prisoner?Source: Agile Retrospectives

Prepare a flipchart with areas for E, S, V, and P. Explain the concept:

Explorer: Eager to dive in and research what did and didn't work and how to improve.

Shopper: Positive attitude. Happy if one good things comes out.

Vacationer: Reluctant to actively take part but the retro beats the regular work.

Prisoner: Only attend because they (feel they) must.

Take a poll (anonymously on slips of paper). Count out the answers and keep track on the flipchart for all to see. If trust is low, deliberately destroy the votes afterwards to ensure privacy. Ask what people make of the data. If there's a majority of Vacationers or Prisoners consider using the retro to discuss this finding.

Discuss the 12 agile principles and pick one to work onSource: Tobias Baier

Print the principles of the Agile Manifesto onto cards, one principle per card. If the group is large, split it and provide each smaller group with their own set of the principles.

Explain that you want to order the principles according to the following question: 'How much do we need to improve regarding this principle?'. In the end the principle that is the team's weakest spot should be on top of the list.

Start with a random principle, discuss what it means and how much need for improvement you see, then place it in the middle. Pick the next principle, discuss what it means and sort it relatively to the other principles. You can propose a position depending on the previous discussion and move from there by comparison. Repeat this until all cards are sorted.

Now consider the card on top: This is presumeably the most needed and most urgent principle you should work on. How does the team feel about it? Does everyone still agree? What are the reasons there is the biggest demand for change here? Should you compare to the second or third most important issue again? If someone would now rather choose the second position, why?

What would make the next iteration a perfect 10 out of 10?Source: Ben Linders

Prepare a flip chart with 2 columns, a slim one for 'Rating' and a wide one for 'Actions'. Everyone rates the last iteration on a scale from 1 to 10. Then they have to suggest what action(s) would make the next iteration a perfect 10.

When the team can't decide between two options, create a big scale (i.e. a long line) on the floor with masking tape. Mark one end as option A) and the other as option B). Team members position themselves on the scale according to their preference for either option. Now tweak the options until one option has a clear majority.

Gauge participants' satisfaction with the retro on a scale from 1 to 5 in minimum timeSource: ALE 2011, Corinna Baldauf

Put sticky notes on the door with the numbers 1 through 5 on them. 1 is the topmost and best, 5 the lowest and worst.When ending the retrospective, ask your participants to put a sticky to the number they feel reflects the session. The sticky can be empty or have a comment or suggestion on it.
